I've mostly been just watching Dota tournaments and speedruns. Getting hyped for EVO here in a couple weeks so if you like Fighting Games that's the event to watch out for. Eswoogi and Distortion are probably my two favorite runners right now but there's no short supply of good runners routing out any of your favorite games.
Eswoogi for good FF9 and FF7 speedruns, he's got great commentary as well. Nice British accent but if I remember correctly you're a Brit yourself Swish so YMMV on that particular point.
Distortion2 for quality Dark Souls speedruns and fight clubs
